When property owners begin researching roof restoration options, one of the most common questions we hear is “What type of silicone coating is the best (Gaco or something similar)?”
Silicone roof coatings have become extremely popular for both residential and commercial properties because they can seal leaks, extend roof life, and delay expensive roof replacements. But not all silicone coatings perform the same.
At All & One Construction and Restoration, we’ve installed silicone coating systems on flat and low-slope roofs such as torch down, TPO, foam, and metal roofs. Based on our real-world roofing experience, some coatings consistently perform better than others.
In this guide, we’ll explain which silicone coatings perform the best, why contractors often prefer Gaco, and when silicone coating is the right solution for your roof.
What Type of Silicone Coating Is the Best (Gaco or Something Similar)?
Many manufacturers produce silicone roof coatings, but the brands we most commonly work with include:
All three manufacturers make quality products, but in our experience Gaco is often the best performing silicone roof coating available.
Why?
Because Gaco coatings tend to be:
• Thicker and more durable
• Highly resistant to ponding water
• Long-lasting under heavy sun exposure
• Designed specifically for roof restoration systems
The downside is that Gaco coatings are usually more expensive than other brands, but the performance and durability often justify the cost.

Why Contractors Often Recommend Gaco Silicone Coating
From a contractor’s perspective, choosing the right coating matters because the coating must protect the roof for many years.
The reason many professionals prefer Gaco when clients ask “What type of silicone coating is the best (Gaco or something similar)?” is because silicone coatings must perform in harsh conditions such as:
• UV exposure
• Ponding water
• Temperature fluctuations
• Expansion and contraction of roofing materials
Silicone coatings like Gaco are designed to remain flexible and waterproof even after years of weather exposure.
According to the EPA, reflective roof coatings can also help reduce heat absorption and improve building energy efficiency.
A Real Case Study: 30,000 Sq Ft Commercial Roof
A great example of why silicone coating can be the right solution was a 30,000 square foot commercial building we worked on that had a torch down roof with multiple small leaks.
The roof itself was still structurally sound, but over time it had developed dozens of small leaks across the surface.
We recently worked on a 30,000 sq ft commercial torch down roof near the City of Industry area that had developed multiple small leaks across the surface. This type of roof issue is very common in commercial properties we service throughout nearby La Puente communities such as Valinda, Avocado Heights, West Puente Valley, Hacienda Heights, and South San Jose Hills.
Instead of recommending a full roof replacement, which would have been extremely expensive, we recommended a silicone roof coating system using Gaco products.
By repairing the seams, preparing the surface properly, and applying a silicone coating system, we were able to:
• Seal the leaks
• Protect the existing roof membrane
• Extend the roof life significantly
• Save the property owner a large amount compared to a full replacement
This is a perfect example of when silicone coating works extremely well.

When Silicone Roof Coating Is the Best Solution
Silicone coatings are not meant to replace every roof, but they work extremely well when the roof is still structurally sound.
Situations where silicone coatings perform best include:
• Minor leaks
• Aging roofing membranes
• Ponding water issues
• UV damage
• Extending the life of an existing roof
When applied properly, silicone coatings can extend the life of a roof by 10–15 years or more.
Organizations like the California Contractors State License Board (CSLB) recommend working with licensed contractors when performing roofing work.
When Silicone Coating Is NOT the Right Solution
While silicone coatings are extremely effective, they are not a solution for every roof.
A coating will not fix problems such as:
• Rotten roof decking
• Major structural damage
• Multiple failing roof layers
• Severely deteriorated roofing systems
In those cases, a roof replacement may be necessary instead of restoration.
A professional inspection is always the best way to determine which option is appropriate.

Why Proper Roof Preparation Matters
One of the biggest reasons silicone coatings fail is poor preparation work.
Before applying a silicone coating system, contractors must:
• Clean the roof thoroughly
• Repair seams and penetrations
• Fix cracks and weak areas
• Allow the surface to dry completely
If these steps are skipped, even the best silicone coating products can fail prematurely.
This is why professional installation is critical.
Is Silicone Roof Coating Right for Your Roof?
If you own a property in City of Industry or nearby areas of La Puente, silicone coating may be an excellent way to extend the life of your roof without the cost of full replacement.
However, every roof is different.
The best way to determine whether coating is the right option is to have a professional roof inspection.
